Claims. (Cl. 189--o5) This invention relates to window structures andembodies,more specifically, improved components employed in metallicwindow structures to provide a weather tight assembly.

For many years, metallic window structures have been standard inbuilding operations involving large structures such as ofiice buildingsand the like, the material of these metallic windows usually beingsteel. In recent times, light metals such as aluminum have been found tobe particularly well suited to building structures, and windowstructures havebeen made out of such materials. For example, incopending application Serial No. 436,191, filed June 11, 1954, by HermanC. Knebel, a metallic window structure is disclosed which isparticularly susceptib le of being manufactured from the lighter metalssuch as aluminum.

in metallic window structures such as discussed above, it is always aproblem to provide suitable structure for rendering the windows weatherresistant. Accordingly, it is an object of the present invention toprovide structure serving to weather proof metallic window structures.

It is another object of the invention to provide a weather strip sealerwhich forms an effective seal with any surface it may engage.

It is a further object of the invention to provide metallic windowstructure in which a variable width mullion may be formed to accommodatestandard size windows.

These and further objects of the invention are accomplished by disposingat sliding points of contact between metallic window sash and supportingstructure novel weather stripping in engagement with an elongatedweather strip sealer. The latter element is formed of resilient materialand provided with longitudinal forward- 1y facing ridges on a resilientpreferably arcuate portion enclosing a longitudinal cavity, such sealercooperating with weather strip having aflat surface urged against theridges. In' addition, the weather strip sealer may be employed in otherapplications such as in the head and sill structure in order torenderthe entire window weather tight. If desired, a stiffening liner may bedisposed in the weather strip sealer.

In order to accommodate windows of standard sizes, a further novelfeature of the invention comprises the use of a selected one of aplurality of mullion forming means to space back to back jambs togetherto form a mullion of variable width.

These and further objects and advantages of the invention will be morereadily understood when the following description is read in' connectionwith the accompanying drawings in which:

Figure 7 is a perspective view, partially broken away, illustrating theweather strip sealer of Figure 6 and Figure 8 is a perspective viewshowing the weather stripping of Figure 6.

Referring to an illustrative embodiment of the invention andparticularly to Figure 1, an upper sash 10 and a lower sash T1 areslidably mounted in a conventional window frame formed by a head 12, asill 13, and jambs IJ-i and 15 joining the ends thereof. The foregoingstructure may be mounted in masonry 16 (Figures 2 and 3) in anyconventional fashion such as by means of head strap hangers T7 and sillstrap hangers 18, for example.

As best shown in Figure 3, the jamb 14 is formed of side plates 19 and20 joined by a U-shaped support 42, an outer plate 21, and an angledinner plate 22, all formed integrally as, for example, by means ofextruding the metals in a conventional manner. Caulking compound 23seals the outer plate 21 to the masonry 16 and in order to furtherstrengthen the structure, side strap hangers 24, joined to the masonry16 in any desired manner, may be fastened to the side plate 20 by meansof nut and bolt combinations 25.

The inner extremities of the outer and inner plates 21 and 22 are formedwith channels 26 and 27, respectively, provided with inwardly extendingflanges 28 and 29, respectively, on opposite sides of the channels.These are shaped to receive elongated pieces of weather strip sealer 36as will be apparent from Figure 6.

The weather strip sealer 30, best shown in Figure 7, is formed of aresilient material such, for example, as natural or synthetic rubber,and comprises a relatively thin preferably arcuate front portion 31enclosing a longitudinal cavity 32, the remainder of the cavity beingdefined by angled walls 33 and 34 forming the inner surfaces of arearwardly extending block 35. Shoulders se and 37 are found on theblock 35 and cooperatewith the flanges Z8 and 29 in the channels 26 and27, respectively.

In order to provide an effective seal with a surface it engages, theweather strip sealer 30 carries on the arcuate portion 311 a pluralityof longitudinal forwardly extending ridges 38. Preferably, the entiresealer 30 is an integrally molded piece as shown in Figure 7. Ifdesired, a C-shaped iiner 39, preferably formed of springy metalalthough other suitable materials may be employed, may be inserted inthe cavity 32 to back the arcuate port-ion 31 and lend greater stifinessto the entire sealer 30 and extend its useful life. It should, however,be understood that the liner 39 may be omitted in the event sufficientstifi'ness is obtained by using the sealer 30 alone. For example, it hasbeen found that the metal liner may be omitted from the sealer 30 inmost instances when it is employed as shown in Figure 6.

In the central plane of the jamb, a parting bead 40 is supported by aU-shaped snap bracket 41 cooperating with the U-shaped support 42 whichjoins the side plates 19 and 2t). Integral with the bracket 41 arechannel closure plates 43 and 44 extending obliquely to the transverseplane of the inner extremity of the parting bead 40 and then extendingparallel to the side plates 19 and 20 to lie in spaced relation to theadjacent edges of the outer and inner plates 21 and 22, respectively.

It will be apparent that the assembly constituted by the parting bead40, the bracket 41 and the plates 43 and 44 may be snapped into positionon the support 42 to form substantially enclosed parallel channels 45and 46 within which are positioned spring balances 48.

Returning to the parting bead 4% it will be seen that it is formed in agenerally T-shaped section to provide channels 49 and 50 formed withinwardly extending flanges 51 and 52, respectively, which receiveelongated pieces of the weather strip sealer 30.

The sash structure adapted to be used in connection with theabove-described jarnb structure is illustrated in Figures 2 and 3 andincludes the upper and lower sashes and 11. The sides of each of thesashes it) and If include recesses 53 and 54 formed with shoulders 55and 56, respectively, plates 57 and 58 extending therefrom parallel tothe planes defined by the outer vertical edges of the sashes 10 and 11but slightly removed toward the central vertical sash plane.

Secured in the recesses 53 and 54 is weather stripping 60, bestillustnated in Figure 8, formed of a strip of spring like metal.Preferably, one edge of the strip is bent back on itself to form a helm61 while the other side of the strip it bent to form an obtusely angledsection 62;. A further bend in the strip provides for an obliquelyextending section 63 which cooperates with the shoulders 55 and 56 tosecure the weather strip 68 in the recesses 53 and 54.

As clearly shown in Figure 6, the weather strip 60 engages the Weatherstrip sealer 30 and, due to the obtuse angle between the main body ofthe strip 60 and the section 62, the strip 60 is resiliently urgedagainst the ridges 38 in order to effect an eflicient weather resistantseal between the sash and the jamb structure. It will be apparent fromFigure 6 that since the weather strip 60 provides a surface extendingsubstantially beyond the sealer 30, small differences in the sizes ofthe sashes 19 and 11 and the jamb structure will not interfere with thissealing action. In addition, the ridges 38, which would normally definean arcuate path, are urged into a straight path by the strip 60 whichdepresses the sealer 30. As indicated in Figure 6, the strip 60 ispreferably spaced a small distance from the plate 58 in order to aid incushioning the sash.

Referring to Figure 2, the meeting rails of the sashes 10 and 11 aresealed by means of a flange 64 adapted to be received within alongitudinal pocket 65 within which weather stripping 66 is provided.Additional weather stripping 67 may be employed, if desired, to insure atight joint between the sashes 10 and 11.

Transversely extending recesses 68 and 69 formed in the bottom rail ofthe lower sash 11, similar to the recess 26, receive the weather stripsealer 30 in order to weather proof the joint between the sill 13 andthe sash 1f. Preferably, the metal liner 32 is disposed in the stripping38. In addition, transverse recesses 78 and '71 are carried by the head12 and receive pieces of the weather strip sealer 30 which cooperatewith vertical surfaces on the upper sash 10 to effectively seal thisjoint. The remaining portions of the sashes 10 and 11 are formed in anydesired fashion in accordance with conventional practices.

Examining the structure illustrated in Figure 4, a mullion formed fromjambs and 15a is illustrated, the jamb 15a being identical to the jamb14 and the jamb 15 being slightly modified to provide side plates 19aand a. Interposed between the side plates 19, 19a and 20, Ztla aremullion forming members 72 which cooperate with the jambs 15 and 15a tospace them a desired distance apart.

More specifically examining one side of the mullion, a plate 73 formsthe head of the member 72, a transverse strip 74 being integral with thehead 73 and contiguous to the plate 19a. The strip 74 is sealed by a 4resilient sealing strip 75 supported by a flange 76 on the plate 19a. Anoffset portion 77 of the member 72 lies contiguous to the plate 19between a flange 78 formed thereon and a T-shaped flange 79 extendingfrom the plate 19a. Provided between the flange 7'8 and the head 73 is afurther rubber sealing strip 80. Leading from the offset portion 77 is aleg 81 effectively locked into the T-shaped flange 79. In otherrespects, the companion parts of the mullion follow the window structuredescribed above in connection with Figure 3.

In fitting the jambs 15 and 15a together, the members 72 are firstlocked to the plates 19a and 20a and subsequently, the jamb 15 urgedinto position as shown in Figure 4. It will be apparent that thestructure illustrated in Figure 4 provides a mullion having the leastpossible width since the T-shaped flanges 79 abut the plates 19 and 20.

Turning next to Figure 5, in the event it is desirable to provide amullion of greater width to accommodate standard size windows in someparticular installation, a mullion forming member 72a, similar in manyrespects to the member 72, is provided to space the jambs 15 and 15a.Since in this instance a mullion of greater width is desired, the plates19, 19a and 20, 20a must be spaced further apart and accordingly, heads73a must be of greater width than the heads 73 and the offset portions77 must be divided into two portions 77a and 77b to engage the flanges78 and sealing strips 75a, respectively. In addition, legs 81a cooperatewith the T -shaped flanges 79 in order to lock the members 72a to thejambs 15. Of course, mullion forming member provided with heads 73 ofany width may be employed to form mullions having any desireddimensions.

From the foregoing, it will be seen that a window structure is providedthat may be simply formed from metallic sections and rapidly assembled.In addition, this structure provides for effective weather tight sealingbetween the sash and jamb structures under all conditions and regardlessof small size variations in the manufacturing operations. Furthermore,mullions of varying widths may be formed in order to accommodatestandard size windows.

It will be apparent that while metal structure has been referred to indescribing an illustrative embodiment of the invention, certain plasticmaterials may serve satisfactorily in view of the facility with whichthey may be extruded. Moreover, it will be understood that theabovedescribed embodiments of the invention are illustrative only andmodifications thereof will occur to those skilled in the art. Therefore,the invention is not to be limited to the specific apparatus disclosedherein but is to be defined by the appended claims.
